Sir,
on 07/03 cbse math exam were taken, but one question was out of syllabus of set 1, sec -D of question 28, this question was from identity . I solve ncert, rd sharma, rs agarwal and cbse previous year question but i never find this type of identity. Also sir set 1 is very very hard as compared to set 2 or 3.
So i request you to give bonus marks on this question, as no student were able to solve this. Also i try several times but cannot able to solve this question.
Thanking you.
Cbse student -adarsh
